The State Highway Administration will conduct several traffic stoppages tonight and tomorrow night on Interstate 95 as it removes steel beams as part of the demolition of the Old Gunpowder Bridge to make way for the Intercounty Connector.

The agency expects to stop traffic on the interstate just north of the Route 212 interchange (Exit 29) three to four times each night for intervals of  about 15  minutes. The stoppages are  expected to occur between 11 p.m. and 6 a.m. in the northbound lanes and between 11 p.m. and 5 a.m. southbound. Variable message signs have been installed to warn motorists of the closings.

Overnight travelers would be wise to use the Baltimore-Washington Parkway or U.S. 29 as alternate routes.
